4-year-old boy accidentally shot himself in the head with dad’s gun while his mum allegedly smoked weed in the car.

A minor has shot himself in the head after finding his dad’s gun in the backseat of their car and started playing with it.

Jarion Walker, 4, according to reports, was sitting in the backseat with his two younger siblings when the unfortunate incident happened in Westwego, near New Orleans, United States.

The boy was rushed to the hospital where he succumbed to injuries on Saturday, January 29.According to a police report, the mother was in the front seat smoking weed with another grown-up.

“It was a contact wound to the forehead, right above the right eyebrow,” Coroner Gerry Cvitanovich said.

“I don’t think it was appropriate to make an arrest at this point. They just lost a child and it certainly wasn’t intentional by any means. It is understood that the boy found the gun underneath the seat”. Mr Lopinto added.
